Video Scaler with Electronic Keystone Correction

The VSC-2 is a high quality polyphase scaler including electronic keystone correction which has been optimized for video and graphics applications. The scaler may be used in conjunction with the VPC-1 Video Processor and Deinterlacer IP core or with any other customer or third party IP. Support for both shrink and zoom modes allows full screen display of any video or graphics source as well as arbitrary resizing for PIP applications. Dynamically loadable coefficients provide maximum flexibility to further optimize for different sources types and to enable effects such as image sharpening. In addition, the core includes a number of Verilog parameters that allow it to be tailored at build time to satisfy specific requirements. Flexibility, robust design and rigorous testing combine to make the VSC-2 ideal for both consumer electronic and projection applications.

The VSC-2 includes complete Verilog source code, Verilog test bench and bit-accurate C models as part of the license. Integration and programming guidelines are also included backed up by expert technical support.

The VSC-2 is available on Crucial IP’s FPGA development platform for demonstration and evaluation purposes. The platform includes a microcontroller to facilitate control of the IP core from a host PC. Perl scripts are provided for ease of setup and serve as clear templates for the programming model. An interactive monitor program is also included.
